Просьба добавить возможность изменения вот этих параметров usermod:
      -e expire_date
              The date on which the user account will be disabled. The date is specified in the format YYYY-MM-DD.

       -f inactive_days
              The  number  of  days  after  a password expires until the account is permanently disabled. A value of 0 disables the
              account as soon as the password has expired, and a value of -1 disables the feature. The default value is -1.

       -L     Lock a user's password. This puts a '!' in front of the encrypted password, effectively disabling the password.   You
              can't use this option with -p or -U.

       -U     Unlock  a user's password. This removes the '!' in front of the encrypted password. You can't use this option with -p
              or -L.
